Q

What propellants are generally used in MDIs?

A

HFAs

17
Q

Approximately how much drug from an MDI plume ends up in the lung?

A

20 percent

18
Q

describe an open tube spacer.

A

the simplest design; sole function to increase distance

19
Q

What brand is an open tube spacer?

A

AeroChamber

20
Q

Describe a reservoir spacer.

A

aerosol directed into a chamber that holds the plume

21
Q

What brand is a reservoir spacer?

A

InspirEase

22
Q

Describe a reversed flow spacer.

A

plume directed against inhalation flow for increased propellant evaporation, completely breath activated

23
Q

What is the general function of a spacer?

A

increase distance between nozzle and oropharynx to allow propellant evaporation, smallest particle size, and better hand-lung coordination by decreasing velocity

24
Q

What are 3 DPI designs?

A

twisthaler/turbuhaler, spiriva handihaler, diskus

25
Q

What brand products use the twisthaler design?

A

symbicort, pulmicort, oxeze

26
Q

Describe the handihaler.

A

a reloadable device that uses blister pack capsules

27
Q

Describe the diskus DPI design.

A

disposable DPI that uses unit-dose blister-pack capsules

28
Q

What brands use the diskus design?

A

serevent, flovent, advair

29
Q

What particle size does an MDI produce?

A

a reproducible range
